SUCTION-BOX.

Specification of Letters Patent.

Patented Sept. 20, 1910.

Application filed June 24, 1909. Serial No. 504,180.

To all whom it may concern:

Be it known that I, DANIEL S. ZIMMER- MaN, a citizen of the United States, residing at. North Water Gap, in the county of Monroe and State of Pennsylvania., have invented a certain new and useful .Improvementin Suction-Boxes, of which the following is a specification.

My invention relates to a new and useful improvement in suction boxes, of that class which are used with paper making machines combination of elements hereinafter set' forth and then specifically designated by the claims.

In order that those skilledin the art to 'which this invention appertains may understand how to make and use the same, I will describe its construction in detail, referring by letter to Athe accompanying drawing 'forming a part of` this specification, in which- ,Figure 1 is a detail sectionl of my 1m,- proved suction box. Fig. 2, is a section at the line :v -:cof Fig. 1 looking in the direction of the arrow. Fig. 3, a section at the line g/-jz/ of Fig. 1 looking in the direction of the arrow. Fig.4, an end view thereof, a part of the stand being broken away. Fig. 5, is a vertical section of one ofthe stands. Fig. 6, a sideelevation thereof. Fig. 7, is a dia-grammatical view showing how the Fourdrinier wire passes over the suction boxes. Fig. 8, a sectional view of my moditied form of suction box. Fig. 9, a section at the line :1cof Fig. 8 looking in the direction of the arrow. Fig.,10,a section at the line ga/-y of Fig. 8 looking in the direction of the arrow.

In carrying out my invention as here veinbodied, A represents a suction box composed of' two cylinders B and C, one within the other.

The cylinder C has a slot D cut 1n one side thereof for the reception of water, pulp or other particles which may be drawn from the material being made into paper while passing over the Fonrdriner wire. This slotl) may be made smaller or larger by means of the plug E, which is adapted to be moved backward or forward as the case may be, by means of the shaft F which is connected therewith by means of the brace G, and when this plug is at its inward extremity, as shown in Fig. 1, that part of the slot D which this plug does not till will be covered by the plate H. To hold the plug even wit-h the cylinder I provide a track I along a. portion of the side of the slot, into which fit projections formed on the plug E. This cylinder is held stationary in the stands J by means of theadjustable clamp K, through which bolts are threaded for holding the upper part to the lower portion of said clamp. One of the bolt holes in the lower portion of the clamp K is extended a considerable length through said ortion and another hole extended from said bolt hole outward to one side of said clamp through which passes the adjust-ing screw L, by means of which the clamp is drawn backward or forward in its track M, thus the cylinder would be moved backward or forward as the case may be. This adjusting screwV is held in position by means of the brace N, and this brace and also the clamp are fastened to a plate O by means of small bolts. In the plate O is placed a swivel screw P which yisthreaded in the stand J. To operate this screw I provide a threaded wheel Q, which rests on the upper part of. the stand J, and when it is turned the swivel screw turns, gradually threading upward or downward, thus raising or lowering the suction box A.

The cylinder B. whichV revolves about the cylinder Cfis'provid'ed with perforations R extending all the way around the central portion thereof, and through these perforations pass the water, pulp -and other part; cles. To revolve the c linder I provide a sprocket wheel S secure to one side thereof, over which passes a chain T, and this chain passes over a secondI S rocket wheel U, which is secured to the ottom couch roll U, to which' power is transmitted by means of a motor or engine. The width of the a er is regulated b mea-ns of the rubber diiclj( le straps V, whic rest on top of the Fonrdriner wire and pass over suitable wheels f placed at both ends of that portion of the Fonrdriner wire on of the sides of the U shaped cylinder C I form the groove C2, in which I place the wood strips C3, and this will rub against the inside surface of the outer cylinder B, and this will prevent the surfaces of the two cylinders rubbing, whichl will prevent the wear of the same, and as these wooden strips. wear away, they may be readily andeasily replaced with very little expense.

a represents the joint whichl connects the .inside cylinder with the pipe passing to the suction pump. This pump sucks the water, I

pulp and other particles from the inside of the cylinder C through its outlet atone end,

and then expels it into a sewer or a lpipe for returning it to a tank at the head of the paper making circuit. To prevent any of the water or pulp passing out of the opposite end I provide a cap b which threads upon the inside cylinder, thus closing. that,

end except the holethrough which the shaft F passes, which may be packed to prevent any of the material passin' out this way.

In practice, the pulp or making paper which is very wet iscarried ,over the suction box by the Fourdrinier wire, said suction box drawing the water from the pulp. iIn

the old style suction boxes which have been stationary, the wire was drawn over` them andy constantly had to be removed 'because they wore out by the constant friction 'caused by said F ourdrinier wire being drawn over said suction boxes, but by my improved suc- -tion box this will be overcome, as the Fourdrinier wire and the suction box travel ing at the same speed will cause little or no friction. f

'Having thus fully described my :inVentiOn,

what I claim as new and useful. is

1. The combination of a stationary cylinder having a slot cut in the upper portion vattached to the p thereof, a -plug fitted 'in said slot, a plate fastened thereto, .a bracket secured to lsaid plate, a shaft, one end of which is attached to "the bracket, the opposite end passingvto the outside of the cylinder for adjusting said plug, a revolving perforated outside cylinder, a sprocket wheel secured thereto, means for revolving the same, wheelsplaced above the Fourdrinierwire at either end of that portion on which the pulp is adapted to run, rubber deckle straps, adapted to pass over said wheels and rest upon thetop of the Fourdrinier wire, stands, adjustable clamps, swivel screws threaded intov said stands and fastened to said clamps by means of a plate, a' wheel placed about saidswivel screwsl for adjusting the clamp up or down,

a shaft movably attached to the clamp, a

bracket for holding said" shaft in position,

ate, a cap, an opening therein, through which passes one ofthe adjusting shafts, said cap closing onev end .of

the cylinder, and a joint threaded on thev opposite end of the said cylinder, adapted to receive a pipe leading to a suction pump. 2. In a suction box of the character described, an linside cylinder having a slot cut therein, means for holding said cylinder in position whereby the slot will alwaysr'befat the top, a plug placed in said slot, means forv moving the plug backward or forward vinaking the slot longer or Shorter, a revolving perforated cylinderplaced about the first named cylinder means for revolving the same, deckle straps resting uponv the upper surface of the Fourdrinier wire, a cap for closing one endof the cylinder, a joint vconnecting the inside cylinder with a suction pump for withdrawing the. water, 'pulp and other particles from the inside cylinder and means for adjusting the suction boxes up and down or backward and forward.

In testimony whereof, I have hereunto aiiixed my signature in the presence of two subscribing witnesses.
